I know that, but:

That seems sensible. find-library-name's goal is to find an elisp
library. Those are not usually found in files without a prefix.

In other words: when looking for "erc", trying "erc.el" and
"erc.el.gz" seem sensible. When looking for "erc.el", trying "erc.el"
and "erc.el.gz" is still sensible; but to try "erc" is absurd. No,
scratch that: it is a bug :)

Ha, ha. Case-sensitive filesystems make the same sense that
case-sensitive languages: none at all. (Note that Common Lisp is
case-insensitive.)
